Title
An I/O-Sized Adc With Second-Order Tdc And Mom Capacitor Voltage-To-Time Converter
Abstract
We present an I/O-size second-order analog to digital converter (ADC) combined with a time-to-digital converter (TDC) and a voltage-to-time converter (VTC). Our proposed VTC is optimized for metal-oxide-metal (MOM) capacitances, and is charged to the MOM capacitances by an input voltage. In a standard 65-nm CMOS process, a signal to noise and distortion ratio (SNDR) of 50 dB (8 bits) is achievable at an input signal frequency of 78 kHz and a sampling rate of 20 MHz, where the respective area and power are 6468 mm(2) and 509 mu W. The measured maximum integral nonlinearity (INL) of the proposed ADC is 1.41 LSBs. The active area of the proposed ADC is smaller than an I/O buffer. The proposed ADC is useful as an ADC I/O.
